Iran is awash in oil but has little capability to refine it. As a result Iran needs to import huge amounts of gasoline. Refineries are a blight on the environment but can be disassembled easily and cleaned up. Nuclear plants leave waste that we as humans still have no idea of how to store them permanently and 100% safely. And the waste is toxic for centuries. Other countries use the oil for their electricity. Here you have a country to do it for much less cost and environmental impact but they say nuclear is for electricity only. Yea...sure.
